No big Quad meets any more. Its pretty sad. There is an active quad league in the Great Lakes Region. You can contact Aaron Hoover with the team at
Ft. Wayne, IN. They have about 8 league meets every year and skate quad and inline races at all of them.
Jim White might have details on their meet schedule. If you want to race at any of those meets, Lisa Dunham is president of the league. She told me last year that I could come up and skate any of the meets I wanted.
All it takes is interest. We have a bunch of adults here in Nashville that skate quads, most of them are skating inlines at practice but will skate quad nationals this year. The say the best races at quad nationals last year were the old guys. Masters and up were the best.
